The Houston media market anchors the country's most ethnically diverse major metro, where Latino, Asian-American, and Black voters together outnumber non-Hispanic white voters — a demographic tilt that has steadily compressed Republican margins in Harris County since 2016.
Across the recorded series it reached a Democratic high of 75.7 points in 1936 and a Republican high of 26.8 points in 1972. Between 2020 and 2024 the market moved 7.7 points toward the Republican candidate; the 2024 margin was 9.3 points.
A population of 7,791,979, a 34% non-Hispanic-white share, and a median household income of $82,767 describe the market. The market's voting pattern over the last decade is most similar to that of Dallas-Fort Worth and San Antonio.
The media markets whose fingerprint — 2000–2024 trajectory, demographics, ancestry, religion — sits closest to this one, and why.
Twin score (0–100) = weighted cosine between tier-standardized fingerprints: presidential margins 2000–2024 with 12-yr trend and elasticity, ACS income, age, education, population and race, top reported ancestries, and religious adherence — chips name the closest-shared dimensions and the widest gap.
